SPECIFICATION forming part of Lttasratent'm. 630,541, dated August8,1899.

Application inea July 2e, 189s.

To all whom it may concern.-

Be it known that I, ALPHENAs V. HYSORE,

of Richmond, in the county of Henrico and State of Virginia, haveinvented certain newr dipping apparatus, the object of the inventionbeing to provide means whereby the tobacco can be quickly andeffectually dipped and to so construct the apparatus that practicallyall the solution employed can be used, thus avoiding the wasteheretofore occasioned by the necessity of discarding large quantities ofthe solution (when used in prior apparatus) on account of the samebecoming' foul or unduly saturated with the tobacco.

A further object is to construct the apparatus in such manner that itcan be readily cleaned.

A further object is to produce an apparatus of the class stated whichshall be simple in construction ,comparatively cheap to manufacture, andwhich shallbe effectual in all respects in the performance ofitsfunctions.

With these objects in view the invention consists in certain novelfeatures of construction and combinations and arrangements of parts, ashereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a longitudinal sectional viewof an apparatus embodying my invention, and Fig. 2 is a transversesection of the dippingroller.`

A represents a tank or vat which may be made of met-al or of any othersuitable material and supported bymeans of legs 1 atits respective ends.A portion of the bottom of the tank or vat, near the inlet end thereof,is made concave and curved,as at 2. Near the outlet end of the tank orvat standards 3 4 are provided, vin each of which two rollers a b c dare mounted. The lower roller of each pair is mounted in fixed bearings,while the journals of the upper rollers b cl are mount- Serial No.686,926. (No model.)

ed in movablejournal-boxes 5. Semi-elliptical vsprin gs U bear at theirrespective ends on the journal-boxes 5, and the tension of these springsand also the distance apart of the rollers 'ofthe respective pairs ofrollers can be regulated and adjusted by means of screws 7. An elasticbelt or carrier B passes between the pairs of rollers and about an idleroller S, disposed in proximity to the concave portion or curved basin 2of the bottom of the tank or vat, so as to receive material from thebasin and carry it between the pairs of rollers. The rollers of vthelirst pair will be adjusted farther apart than the rollers of the lastpair, so that the tobacco will receive light and greater pressure whenit passes through the last pair, and thus clogging of the mate- 4rialatthe presser-rollers will be avoided and surplus solution will beeffect-ually pressed out of the tobacco. The lower rollers ac areprovided with gear-wheels 9, which receive motion from a pinion 10 andimpart motion to long-tooth gear-wheels 11 on the journals of the upperrollers b d. Motion is imparted to the pinion 10 from a `pinion 12, andthe YAflatter may receive motion from any convenient source of power. I

The sides of the tank or vat, at opposite sides of the concave portionthereof, are protvided with slotted standards 13, between which thedipping-drum 14 is disposed. The rjournals of this drum are mounted injournal- `boxes 15, removablyv disposed in the slotted standards 18. Thejournal-boxes 15 are carried at the free ends of arms 16, which arepivotally supported by the journals of the .upper presser-roller b. Thepi-voted ends of the arms 16 are connected by a depending yoke 17, andthe latter is provided with a horizontal arm 18, on which acounterweight 19 is adjustably secured. By manipulating the weighted arm18 the arms 16 can be turned `on their pivoted supports and thejournal-box `15 and dipping-drum 14 raised, thus permitting ready accessto the partsfor cleaning purposes. If desired, chains e may be attachedto the journal-boxes 15, as shown in dotted lines in Fig. 1, for raisingthe dippingdrum. l

The dipping-drum 14 may be made of wood pressure when it passes betweenthe first pair.

and is covered with a peripheral metal band 20, provided with teeth 21.The teeth 21 are made with curved edges 22, which receive the tobaccoand carry it forward through the dipping solution. Motion is imparted tothe dipping-drum by means of a sprocket-chainf, which receives motionfrom a sprocket-wheel g on a journal or roller b and transmits motion toa sprocket-wheel h on the journal of said dipping-drum. The teeth 2lmove in comparatively close proximity to a curved perforated plate 23,removably disposed under the roller 14 and concentric with the curvedbottom or basin 2 of the tank or vat.

In order to adjust the roller 14 relatively to the curved plate 23,should the teeth 21 become worn, screws 24 are disposed in the slottedstandards 13, and on these screws the journal-boxes 15 rest.

A cross-bar 25 is adj ustably secured at its ends to the arms 16, andfrom this cross-bar a series of teeth 26 project and intermesh with theteeth 21 on the dipping-drum to insure the delivery of tobacco from thecurved plate 23 to the carrier and prevent any tobacco being carried bythe teeth 21 past said carrier.

The tank or vat will be supplied with the usual saturating solution inthe concave portion or basin 2 and the tobacco will be fed between thedipping-roller and plate 23. The tobacco will be carried through thesolution by the teeth 21 and be delivered to the conveyer, as aboveexplained.

By the use of the curved concave bottom or basin of the tank or vat Iamenabled to utilize practically all the solution, and thus effect agreater saving of solution than when a flatbottom tank is used, becausein the latter case a large amount of the solution becomes saturated andfoul and must be discarded.

My improvements are simple in construction and effectual in all respectsin the performance of their functions.

Various slight changes might be made in the details of construction ofmy invention without departing from the spirit thereof or limiting itsscope, and hence I do not wish to imit myself to the precise detailsherein set orth.

Having fully described. my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination of a tank and a vertically-movable counterweightedtoothed drum mounted over the same and adapted to feed material throughliquid contained in said tank.

2. The combination of a tank, a concave perforated plate disposed insaid tank and a vertically-movable counterweighted toothed drum mountedover the tank and adapted to cause material to pass over said plate andthrough liquid contained in the tank, substantially as set forth.

3. In an apparatus for treating tobacco, the combination with a tank, ofa revoluble dipping-drum mounted over the tank and means for raisingsaid dipping-drum, substantially as set forth.

4. The combination with a tank and a removable toothed drum mounted overthe same, of a series of normally stationary teeth intermeshing with theteeth of the drum and means for adj ustingsaid stationary teethrelatively to the drum, substantially as set forth.

5. In an apparatus for treating tobacco, the combination with a tankhaving bearings for ljournal-boxes, of a revoluble dipping-drum,

approximately horizontal arms pivotallysupported at one end,journal-boxes for the drum carried by said arms and mounted in saidbearings on the tank, substantially as set forth.

G. In an apparatus for treating tobacco, the combination of a tankhaving slotted standards, approximately horizontal arms pivotallysupported at one end, a revoluble dipping-drum having its journalsmounted at the free ends of said pivoted arms and adapted to enter saidstandards, substantially as set forth.

7 In an apparatus for treating tobacco, the combination with a tank, ofpivoted arms, a dipping-roller mounted at the free ends of said arms andhaving teeth on its periphery and teeth carried by said pivoted arms andintermeshing with the teeth on the dippingdrum, substantially as setforth.

8. The combination withatank,ofaweight ed lever and a revolubledipping-drum carried by said lever, substantially as set forth.

9. The combination with a tank, of pivoted arms, a revolubledipping-drum carried by said pivoted arms, a yoke projecting from thepivoted ends of said arms and a weighted arm projecting from said yoke,substantially as set forth.

l0. In an apparatus for treating tobacco, the combination with a tank,pairs of presserrollers, means of transmitting motion thereto and aconveyer passing between the presserrollers, of arms pivotally connectedat one end to the journals of one of the presser-rollers, a revolubledipping-drum mounted at the free ends of said arms, and gearing betweensaid drum and one of the presser-rollers, substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
